I’m creating a csv-creating application, where the user just inputs the necessary information and then their browser spits out the necessary csv file. I was wondering if there was some sort of event handler that exists so that I can trigger an alert once a file is downloaded? Ideally I’d want to tell my user that the download finished so they don’t have to keep waiting on that page, because they’re not the most technical users so relying on the download portion on their browsers isn’t as foolproof.
